Procedure

28 g of gelatin and 13.2 g of benzotriazole were dissolved in 3,000 ml of water and then stirred at 40° C., while a solution of 17 g of silver nitrate dissolved in 100 ml of water was added over 2 minutes. The thus-prepared silver benzotriazole emulsion was precipitated to remove excessive salts. Then the pH of the emulsion was adjusted to 6.0 to yield the desired silver benzotriazole emulsion (yield: 400 g).
